VITRITVIUS,1 a Roman architect and engineer, whose full name was MARCUS VITRUVIUS PoLuo, the author of a very celebrated work on architecture. Nothing is known about his personal history, except what can be gathered from incidental remarks in his own writings. Owing to the discovery of a number of inscriptions relating to the Gens Vitruvia at Formi..T in Campania (Mola di Gaeta), it has been suggested that he was a native of that city, and he has been less reasonably connected with Verona on the strength of an existing arch of the 3d century, which is inscribed with the name of a later architect of the same family name - " Lucius Vitruvius Cerdo, a freedman of Lucius." From Vitruvius himself we learn that he was appointed, in the reign of Augustus, together with three others, a superintendent of batistm and other military engines, a post which, be says, he owed to the friendly influence of the emperor's sister, probably Octavia (De A•ehiteetura, i. pref.). In another passage (v. 1) he describes a basilica and adjacent axles Augusti, of which he was the architect. From viii. 3 it has been supposed that he had served in Africa in the time of Julius Caesar, probably as a military engineer, but the words will hardly bear this interpretation. He speaks of himself as being low in stature, and at the time of his writing bowed down by age and ill-health (ii. pref.). He appears to have enjoyed no great reputation as an architect, and, with philosophic contentment, records that he possessed but little fortune. Though a great student of Greek philosophy and science, he was unpractised in literature, and his style is very involved and obscure. To a great extent the theoretical and historical parts of his work are compiled from earlier Greek authors, of whom he gives a list at i. 1 and viii. 3. The practical portions, on the contrary, are evidently the result of his own professional experience, and are written with much sagacity, and in a far clearer style than the more pedantic chapters, in which be gives the somewhat fanciful theories of the Greeks. Some sections of the latter, especially those on the connexion between music and architecture, the scale of harmonic proportions, and the Greek use of bronze vases to reverberate and strengthen the actors' voices in the theatre, are now almost wholly unintelligible.
The De Arch?' tectura is divided into ten books, each with a preface, in which occur most of the personal facts about himself. It is dedicated to Augustus, and that fact is really all that is known with regard to the date at which Vitruvius lived, though many attempts have been made to gather more minute indications from the internal evidence of his writings : for example, the omission of any mention of the Pantheon in Rome has been taken as an argument to show that he wrote before it was built in 27 D.C. This, however, and other arguments of the same kind are obviously of but little weight. Vitruvius's name is mentioned by Frontinus in his work on the aqueducts of Rome; and most of what Pliny says (U.N., xxxv. and xxxvi.) about methods of wall-painting, the preparation of the stucco surface, and other practical details in building taken almost word for word from Vitruvius, especially from vi. 1, though without any acknowledgment of the source.
From the early Renaissance down to a comparatively recent time the influence of Vitruvius's treatise has been remarkably great. Throughout the period of the classical revival Vitruvius was the chief authority studied by all architects, and in every point his precepts were accepted as final. In some cases a failure to understand his meaning led to curious results ; for example, the mediaeval custom, not uncommon in England, of placing rows of earthenware jars under the floor of the stalls in church choirs appears to have been an attempt to follow out Vitruvius's remarks about the advantages of placing bronze vases round the auditorium of theatres. Bramante, Michelangelo, Palladio, Vignola, and earlier architects were careful students of Vitruvius's work, which through them has largely influenced the architecture of almost all European countries down to the present century, a very remarkable instance of the success and influence of a book being actively redeveloped a very long time - about fifteen centuries - after its author's lifetime. There is no reason to suppose that the book was either popular or influential among the ancient Romans, and yet in more modern times its influence has been unbounded. Its archreological value is very great, as without it we should find it very difficult to understand the uses of the various parts of such houses as those at Pompeii, and many interesting details with regard both to construction and design would have remained unintelligible.
Ilk. i. opens with a dedication to Augustus. C. 1 is on the science of architecture generally, and the many different branches of knowledge with which the trained architect ought to be acquainted, viz., grammar, music, painting, sculpture, medicine, geometry, mathematics, and optics ; c. 2 is on the general principles of architectural design ; c. 3 on the considerations which determine a design, such as strength, utility, beauty, and the like ; c. 4 on the nature of different sorts of ground for sites ; c. 5 on walls of fortification ; c. 6 on aspects towards the north, south, and other points ; c. 7 on the proper situations of temples dedicated to the various deities.

The first MS. of the De Architeetura which retracted much attention was a fine codex on vellum preserved in the Benedictine monastery of Monte Cassino. The first printed edition is that issued in ]ionic by George lterolt about 1485-86, but without indication of place or date; it is is small folio with thirty-four lines to the page, and has neither signatures, catchwords, nor numbering of the leaves. It was edited by J. Salpicins, and with it is printed Frontinns De Aqvxductibus; this second work occurs as an addition in many early editions of Vitruvius, of which a very large number were printed at various places in Italy within a few years after the publication of the editioprineeps,3 On the whole the best edition of Vitruvius's text is that edited by Schneider, Lcipsic, 1S07, 3 yds. Sy°, with good Vitruvius names Cicero and Lucretius as "post nostram memoriam nascontes." 2 The architect being at that time also the contractor.
notes, but no plates. An immense number of translations have also been published in most European languages - the first Italian translation at Como in 1521; French, at Paris in 1547 ; German, at Nuremberg in 154S ; and the first English translation in London in 1092. The best English translation is that of Gwilt, IS26, improved edition, 1860. That of Wilkins (1812) is merely it fragment of some of the books, but it is copiously illustrated with engraved plates.
The nanic of Yitruvius has been given to several handsome works on modern architeetme, such as Campbell, Vitrurins Britannicus, London, 1715-71, a series of illustrations of the chief buildings of the 16th century in England, including many works of the brothers Adam ; one of these brothers, William Adam, produced a similar work illustrating the buildings which he had designed for Scotland, of which he was a native, under the title of l'itruries Seoticus, Edinburgh, 1790. Plural, Le Vitenee D«noie, Copenhagen, 1746-49, is a similar collection of modern buildings in Denmark.
The biographies of Vitenvilis as usually m11)11,110(1 are very untrustworthy, and contain ninny statements which rest upon no authority whatever. (J. II. M.)
